This upper-air forecast map from the ECMWF model for the day after Chistmas shows a massive upper-trough and closed-low over the Midwest. The implications are that a significant surface storm will affect the Eastern U.S., with residual cold surface air being slowy eroded by warm winds aloft. This means mostly rain, but there could be some concern for ice over western VA, so trends in the guidance will be monitored over the next week.

It's an exciting night for astronomers, but it may be a let down for Virginians. Tonight, Earth will pass directly between the sun and Jupiter - making Jupiter one of the brightest objects in the sky. Our problem will be the strong possibility of clouds blocking our view (and maybe a few showers). IF we do get enough breaks in the clouds, here's how to get a glimpse...

Jupiter will be opposite the sun, so look to the eastern sky when the sun is setting in the west. THE BEST TIME TO VIEW WILL BE AROUND MIDNIGHT - when you should look toward the southern sky. If you wait closer to sunrise tomorrow you'll have to look in the western sky. Jupiter will be above the brightest star in the constellation "Taurus" called "Aldebaran" - Jupiter will be much brighter.

Earth passes between the sun and Jupiter about every 13 months, but tonight Jupiter will be closest to Earth until another 9 years. It's doubtful the weather will cooperate to get a good view, but it's worth peaking your head out around Midnight if you're still awake.
